Incidentally, I took Finasteride for years and it did nothing to regrow the hair I'd lost in my early twenties. Of course I was taking it for a different reason, but the doctor indicated a positive side affect would be that it might help regrow the hair on my head. Instead I suspect it messed with my sexual powers in a negative way. So even had it worked as he indicated, is it worth risking impotency just to have some hairs on your head?
